Thanks, my bad. I thought that Kindle Touch hacks would install automatically on the PW. My own aims are more modest at the moment, I want to get rid of code2000 rendering of Arabic/Persian. So I am going to try to modify the cramfs image to include a file with the same name (code2000.ttf) but containing a better typeface for Arabic. I need to install a more functional cramfs distribution though, probably its best to do it in linux.
